Answer:
[tex]1 \frac{14}{40} = 1 \frac{7}{20} [/tex]
Step-by-step explanation:
Finding the LCD ang subtracting the whole numbers,
[tex]5 \frac{2}{8} - 3 \frac{9}{10} = 2+( \frac{10}{40} - \frac{36}{40} ) = 2+( - \frac{ 26}{40} )[/tex]
Now we must subract because the calculated value of the fraction is negative
Converting the number to a fraction and getting their LCD,
[tex]2 - \frac{26}{40} = \frac{80}{40} - \frac{26}{40} = \frac{54}{40} = 1 \frac{14}{40} [/tex]
Simplifying
[tex]1 \frac{14}{40} = 1 \frac{7}{20} [/tex]
